from 2013 to 2015. The Office of the Ohio Consumer's Council, under the auditor's advice, requested AEP to disclose additional records, which was, in turn, denied by a PUCO administrative law judge, who agreed with AEP's stance that their confidentiality be protected until the audit process was resolved. Pablo Vegas, the president and chief operating officer of AEP Ohio, insisted at the time that rates are based on actual costs of system operations, solidifying the company's claim that no deceptive action had taken place. A ruling by PUCO in November 2017 reduced the amount of credit a customer could receive for excess electricity sold back into the grid. This reduction in credit applies to people whose systems generate enough electricity to offset all of their use, and still have some electricity left over. On January 10, 2018, PUCO held public oral arguments on the issue. Utilities and opponents are "digging in against each other over proposed changes", and the issue looks likely to head to the state Supreme Court. One of the more contentious sections limits the part of a customer's bill that can be offset by solar panel generation. In a statewide poll of Republican or independents who also say they are conservative, the Ohio Conservative Energy Forum found in 2018 that 87 percent support net metering. South Carolina In South Carolina, residential solar can make up two percent of the energy each utility sells, according to a law passed in 2014. Solar developers and solar advocate special interests argue that the cap stifles further residential solar development in the state. In June 2018, South Carolina lawmakers declined to remove limits on solar in the state during reconciliation of the state's annual budget bill. Developers and renewable advocates criticized state legislators for cutting the proposal from the budget bill. Major utilities in South Carolina are expected to meet the net metering cap this year. Utah The state of Utah offers tax credit for customers of residential solar panels. In February 2017, there was a compromise in the state legislature to phase out the solar tax credit by the year 2021 by limiting how much of a tax credit each person can get. The bill, House Bill 23, was signed in March 2017 by Utah's governor Gary Herbert. In Utah, before the legislation takes effect, rooftop solar customers can claim $2,000 in tax credits. That amount will be reduced by
